Hello all!
I've been trying my hand at leatherworking (after years in model ship building) for a little over a year now. I started out with a cheap large tool kit and have been slowly substituting the tools I use most (or use less often but need to be better quality) for better ones. That's made a huge difference for e.g. stitching (Japanese French-style prickers, a much better diamond awl (can't find a flat one), better needles and thread...), and I'm happy with the quality of leather I have available here. My results are at the point where people I'm not related to are asking for commissions.
HOWEVER, my edge finishing, particularly edge beveling, actually seems to be getting worse over time. I paid too much for a proper Japanese edge beveler (I'm currently in Brazil, so for anything not made locally or in China, triple the price due to shipping and import duties), #1 for 1-1.4mm leather, it came sharpened plus I've stropped it with the sorta-sandpaper that came with it, and I'm following the usage instructions plus guides I've seen online. The moment the beveler touches a project, the project turns to trash.
I'm careful to hold the leather flat, either carefully with the edge of my hand, or with a steel ruler if I'm beveling a straight edge. I only work dry leather, all veg tan, 1-1.4mm thick, sanded (low grit sandpaper, should get around to buying higher grit too), normally before stitching. With a light touch, nothing happens until the beveler gouges a chunk out. With a stronger touch, I get the string of edge leather coming out the back of the beveller, but am left with a very noticeable line in from the edge where the side of the beveler has touched the leather - this can't be avoided since I can't twist the beveler any further away from the topside short of beveling along the edge of a table (which would have its own problems). Typically I get a sawtooth pattern along the bevelled edge this way as well, as the beveller catches on the leather surface and gouges bit after bit. If I make multiple soft passes, the edge typically just looks like it's been gnawed at by an elderly cat.
Is this:
- My incompetence?
- Tools not sharp enough (and I don't seem to ever be able to get anything sharp enough - my half moon knife is practically useless now no matter what I do with whetstone&strop)?
- Tools wrong size or type? (the ones I had from the kit are multiple sizes, but give the same issues as described but to a greater degree)
- Wrong technique?
- Wrong leather?
- Something else?
Could there even be a different technique or tool I could be using to avoid beveling at all? For example, I realised I hate burnishing by hand, so I got a burnishing attachment for my dremel-ish tool, and that works well.
